I've been looking for my iMac a power strip that not only protects against voltage spikes, but also includes a line filter. My iMac always had a certain leakage on the housing, so that I get each time a wipe. That's completely gone with this Header. The line filter protects against induced voltages probably also when the heater in the basement is not decoupled clever and you have radio amateurs as neighbors.
The only thing I want to complain about is the fact that there is no clever holes for attaching eg under a desk. Only on one side there is a groove, so that one can use a screw to fix. When the size of the bar I would have found useful.
